Build A Chrome Extension for Amazon to eBay Drop Shippers To Find Hot Selling Products With Margin

I am looking for a Chrome Extension to be built for Drop Shippers who sell Amazon products on eBay. This extension needs to find Amazon products that are selling on eBay and scrape the titel from Amazon, search eBay for a match and feed back live information to see if it it a viable product to Drop Ship. This will require Amazon and eBaby API and Scrapers. The user will open Amazon on chrome browse items for sale then click the extension and it will search eBay for a match and display on the amazon site when a match is found for all items for sale on that page the following... 1. Average % price difference from eBay sales to Amazon 2. Units sold on eBay in the last 30 days 3. Be able to scrape the ASIN 4. Be able to scrape and extract the ASIN & URL then user to be able to select chosen items on page as CSV File This is the basics and more development will be required in the future. This needs to be a PayPal Subscription Extension so payment method will be required also. I use one Chrome extension that does this the other way. It will check products on eBay and compare them on Amazon and give results but i am looking for the other way round. This extension is called Intellyfish - I have attached a screen grab of Intellyfish, I want this result but on Amazon but taken from average SOLD price on eBay. Any questions PLEASE ask. Thank you
